New uvbyß photoelectric photometry of the short-period variable star V1719 Cygni (HD 200925) has been secured. A period analysis of these data and those reported in the literature has provided us with stable pulsation frequencies that fit all the available observations covering a time span of 20 yr. The frequencies determined are 3.7411556, 7.4823111, 11.2234667, and 4.6777749 cycles day-1 and of smaller amplitude 8.4189900 cycles day-1. It was found that this Population I star has log g around 3.1 and an effective temperature of 6750 K.
